VINEYARD HARROW.

SPECIFICATION forming part of Letters Patent No. 655,859, dated August14, 1900. Application filed March 28, 1900. Serial No. 10,481. (Nomodel.)

To all whom it may concern:

Be it known that I, JOHN F. FAY, a citizen of the United States,residing at Geyser-ville, county of Sonoma, State of California, haveinvented an Improvement in Vineyard-Harrows; and I hereby declare thefollowing to be a full, clear, and exact description of the same.

My invention relates to an apparatus which is designed for cultivatingthe ground in vineyards.

It consists of acentral draftbar, aplurality of parallel timbers hingedto the front of said draft-bar and connected by links with the rear endthereof, so that they may he tilted at any angle with relation to thecentral bar, a yoke fixed upon said central bar, leverarms fulcrumed insaid yoke and slidably connected with the rear ends of the divergentframes, a centrallvfulcrumed lever passing between the arms of the saidfulcrumed yoke and having loose connections with the levers, and a rackmechanism whereby said actuating-lever maybe adjusted to rigidly holdthe barrow-frames at any angle with relation to the draft-bar.

My invention also comprises means for securing the harrow-framestogether and details of construction, which will be more fully explainedby reference to the accompanying drawings, in which Figure 1 is aperspective view. end elevation.

The object of myinvention is to provide a harrow which is especiallydesigned to be used in vineyards. For such purposes it is nec essarythat the side frames of the harrow carrying the teeth should beadjustable to stand at different angles with relation to the centralsupport and the ground over which they travel and that they should berigidly held in any position at which they are set, It is the object ofmy invention to provide such an apparatus that these results can beeffected. A is a central bar, to the front of which a clevis 2 is fixedfor the attachment of the team or power by which the harrow is drawn.Upon each side of the central beam are the frames 3 4, to which thebarrow-teeth are fixed. These frames are here shown as two in numberupon each side, and the bars of Fig. 2 is an each frame are securedtogether at the front by angle-braces 6, which hold them. firmly withrelation to each other, one arm of these braces standing, essentially,parallel with the 5 5 central beam, having the outer end fixed to theouter timber, the angle to the central timber, and the short armextending at right angles therefrom and also fixed to the outer timber.The rear ends of these pairs of bars are secured together by transversebars 8, which are also firmly bolted or secured to the timbers, so as toform the pairs upon each side into single structures. These pairs ofteeth-carrying timbers are connected to the front end of the bar-beam Aby hooks 9, fastened to the beam, and plates 10, secured to theouterframe-timbers, having holes in them which allow them to swivelfreely upon the hooks, or other equivalent turnable connec- 7o tions maybe employed.

Across the rear end of the beam A is fixed a bar 11, the outer ends ofwhich have a plurality of holes made through for the reception of theinner ends of links 12, the outer ends of which are connected with thetransverse bars 8, which unite the rear ends of the toothframes. Theselinks are freely turnable at their inner connections with the transversebar, and the bars to which the outer ends are connected are also looselyturnable upon the links, so that the harrowframes may be turned up ordown about their points of connection and made to stand at any suitableangle with relation to the ground and the central beam. In order toretain these toothframes at any desired angle and make the structurerigid when set for Work, I have shown a yoke 14, fixed transverselyacross the rear of the beam A and having upturned 9o ends which formfulcrum-points for the bent levers 15. The outer ends of these leversextend across the tooth-carrying frames 3 4 and are slidable throughholes in upturned. plates 16, which are secured to the barrow-framesessentially in line with the yoke and the vertical plane of the levers.These lever-arms are freely slidable through these plates, so that whenraised or depressed the harrowframes may accommodate themselves to thetoo movements of the levers. The inner ends of the lever-arms passthrough and are slidable in the bent arms 18, which are fixed to thelever 19. The front end of this lover is fulcrumed upon a standard 20,fixed to the beam A and extending upwardly therefrom. The rearend of thelever extends behind the frame and has a suitable handle and is alsoprovided with a spring-pressed latch 21, the end of which is adapted toengage with a curved rack 22. This rack is bolted or otherwise securedupon the rear end of the timber A, and for the purpose of making itstifi and rigid it is curved over at the top and the end carried downand bolted to the timber A at a point in front of the other attachment,so that it forms in a single structure a brace for itself, which willpreventits being moved out of position.

The harrow frames 3 4: are adjusted to travel between the rows of vines.When a vineyard is plowed, by commencing in the center between the rowsof vines the earth is thrown up into a ridge in the center and slopesoff on each side toward the rows of vines. When the earth is thrown tothe vines, the plowman commences close to the rows and plows toward thecenter, where there will be a deep dead furrow. In either case it isnecessary to set the harrows to the planes of the earth either convex orconcave and to lock them so that the weight will act upon all partsequally.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. The combination in a harrow of a single longitudinally-disposeddraft-beam, parallel tooth-carrying beams having a single hingeconnection with the front of the draft-beam, said tooth-beams divergingrearwardly from the point of attachment, link connections between therear of the beams and the rear of the draft-beam, and a lever andmechanism connecting with the tooth-beams whereby the latter mayberaised or depressed, and a lock- 1 with draft attachments, a pluralityof paraljlel tooth-carrying beams located upon each ing mechanismtherefor.

2. In a harrow, a centrally-disposed draftbeam, parallel tooth-beamssecured together in pairs upon oppositev sides of the draftbeam, asingle loose connection between the front of said beams and the front ofthe draftbeam, said tooth-beams diverging rearwardly from thedraft-beam, a bar secured to the rear of the draft-beam, links looselyconnecting said bar with the rear of the tooth-beams, a standard mountedupon the draft-beam having a lever fulcrumed thereto and extendingrearwardly, a yoke fixed to the draftbeam, levers fulcrumed thereinhaving the outer ends loosely connected with the toothbeams, and looseconnections between the inner end and the lever whereby the toothbeamsmay be raised or depressed.

3. The combination in a harrow of a longitudinally disposed draft beam,parallel tooth-beams secured together in pairs having hand.

the front ends loosely connected with the front of the draft-beam, andthe rear ends diverging therefrom, links by which the rear ends of saidtooth-beams are loosely connected with the rear of the draft-beam, ayoke fixed upon the draft-beam, bent levers fulcrumed in said yoke withthe outer ends slidable in brackets which are secured to the toothbeams,a lever fulcrumed in front of said yoke, extending rearwardly, saidlever havinglugs or brackets upon the sides with holes through which theinner ends of the/transverse levers are slidable, a vertically-disposedrack fixed upon the rear of the draft-beam, and a spring-pressed pawlcarried by the handle adapted to engage with the rack whereby theharrow-frames may be tilted and maintained at any angle with relation tothe draft-beam.

4. In aharrow, a central longitudinal draftbeam, divergent tooth-beamsloosely connected with the draftbeam at front and rear, a lever,intermediate connections and locking-arms whereby the tooth-beams may betilted and rigidly locked with relation to the draft-beam, andangle-iron plates fixed to the front ends of the tooth-frames andtransverse plates across the rear ends whereby the parallelism of saidframes is maintained.

5. The combination of the draft-bar of a harrow with means forconnecting the parallel divergent tooth-frames of a harrow, consist: ingof metallic plates extending transversely across the rear ends of saidbeams and bolted thereto, angle-plates, the outer ends of which arebolted to the outer tooth-frame, and the angles are bolted to the innertooth-frame so that the longerarms of said plates are approximatelyparallel with the draft-bar, and

loose connections whereby each pair of beams has a single connectionwith the draft-bar at 3 each end.

6. In a harrow, a central longitudinal beam side of the draft-beam anddiverging from front to rear with relation thereto, angleplates by whichthey are rigidly secured together at the front, and transverseunitingplates at the rear, loose link connections between the front andrear ends of the toothbeams and the draft-bar, a lever fulcrumed I atthe rear of the draft-bar connections between the tooth-beams and saidlever where- I by the tooth-beams may be tilted to stand at an anglewith the draft-beam and means for locking said beams rigidly withrelation to each other.

In witness whereof I have hereunto set my JOHN F. FAY. Witnesses:
